aquatherm flexi system is a new class of polyethylene raised temperature type 2, a recyclable side chain thermo plastic for in wall installations in houses apartments etc.

Flexi utilises compression sleeve connections, recognised as a permanent joint using DR fittings and compression sleeves to complete seamless jointing and also to aquatherm green larger dimensions.

Care must be taken with expanding tooling, aquatherm uses a locked expanding head so that incorrect expanding tools will not over expand.

Only used brand matched aquatherm expanding tool and expanding heads….following the connection technique guidelines…remember to expand once, turn and expand again…..when expanding make sure the sleeve is well clear of the expander (outside the expansion zone to ensure there is no risk of damaging tool and pipe).

 

Key points to remember

• Don’t mix other expanding heads and tools. Keep it brand matched
• Keep the expander heads well oiled, and free from dirt and site material that could mis- function the expander
• Any white cut marks after expansion are a clear indicator that you have an expander that requires attention and is over expanding
• Extra care should be taken when expanding in cold conditions i.e. 6 degrees and lower
